Dear Lewis and Sebastian and people involved in this discussion

You can also try to find the others GPI linked molecules defect on white blood
cells.
For example using a double staining with CD15 and CD16 on neutrophils, CD64
and CD14 on monocytes. CD15 and CD64 molecules are not GPI linked and so, can
be used to gate respectively the PMN and monocytes cell populations. It is now
very easy to see if the CD16 and CD14 are or not, expressed in cells of your
PNH patient. Take care that some monoclonal antibodies against the CD16
molecule, recognise a molecule not GPI linked. This is a very simple
alternative to CD55 and CD59 quantification on red blood cells, for example,
following a red blood cells transfusion.
Success
